Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a battery case, and more particularly, to a battery case that allows relatively long cylindrical batteries to be easily stored and taken out with a simple structure.

[Conventional technology]

Generally used battery cases use a separate tape to remove the battery. The battery is stored with the tape on the bottom side of the battery, and when removed, the tape is pulled to pull up and remove the battery.

In addition, as another method, a battery case has been proposed in which a step is formed at the bottom of the battery case, and when taking out the battery, one end of the battery is forcibly pushed down with a finger and the battery slides into the step, thereby tilting the battery. There is. For example, it is disclosed in Utility Model Publication No. 47-41707.

[Problems that the invention attempts to solve] Regarding battery cases that use conventional tape,
When storing the battery, care must be taken so that the tape is always on the underside of the battery, and care must also be taken when attaching the lid so that the tape is not exposed to the outside. Therefore, it is very troublesome to store the battery, which is not very desirable.

In addition, in the case of a battery case with a stepped portion,
To remove the battery, it is necessary to open the lid and then use your fingers to push out the battery. Therefore, there was a problem in that the removal operation was quick and easy.

Therefore, the purpose of the present invention is to have a simple structure,
Another object of the present invention is to provide a battery case in which the battery removal operation is quick and easy.

[Means for solving problems]

In order to achieve the above object, according to the battery case of the present invention, a recess is formed in the bottom of the battery case on one side in the longitudinal direction of the battery to be stored, which is deeper than the other, and a lid that covers the opening for attaching and detaching the battery is provided. is pivotally supported to be openable and closable at the end of the opening on the side of the recess, and is attached so as to be vertically movable toward the recess in a state of opening approximately at right angles to the longitudinal direction.

[Effect]

According to the battery case configured as described above, when taking out the battery, the lid is rotated to an angle substantially perpendicular to the longitudinal direction of the battery to open the lid. Thereafter, by pushing the lid downward, the lower end of the lid comes into contact with the top surface of the battery. By further pushing the lid downward, one end of the battery is pushed into the recess and the other end pops out of the opening, allowing quick and easy removal of the battery.

〔Example〕

A preferred embodiment of the battery case of the present invention will be described below with reference to FIGS. 1 and 2.

FIGS. 1 and 2 are perspective views of the battery case of the present invention integrated into the main body of an electrical appliance, toy, etc., showing the state with the lid closed and the state with the lid opened, respectively.

Reference numeral 1 in the figure indicates the main body of an electric appliance, toy, etc. not specified here, and reference numeral 2 is attached to this main body 1 as a whole.
The battery case shown in is integrally formed.

This battery case 2 houses a battery 3,
(See FIG. 2), its anode and cathode are electrically connected to known terminals (not shown). Now, in the bottom part 4 of the battery case 2 in which the battery 3 is housed, a recess 5 which is relatively deep is formed at one end in the longitudinal direction of the battery 3. Therefore, one end of the stored battery 3 (the cathode side in the embodiment) is held floating above the bottom 5.

Further, a lid 7 is attached to the opening 6 of the battery case 2. A handle 7' is located approximately in the center of the top surface of the lid 7.
is provided, and one end is provided with a pawl 8 that engages with the main body 1 when closed. This lid 7 is pivoted to the battery case 2 at the other end, that is, the end of the opening 6 on the side of the recess 5 . In this embodiment, this pivoting structure is realized by a pin 9 formed on the lid 7 and a through hole 10 formed on the battery case 2 side. The through hole 10 is formed by a portion 11 extending in the longitudinal direction of the battery 3 and a portion 12 extending in the direction of the lower recess 5 .

The through-hole portion 12 is located closer to the anode than the cathode end of the battery 3 in the housed state. Therefore, as will be described later, when the lid 7 is pushed downward along the through-hole portion 12 as shown by the arrow, the lower end 1 of the lid 7
3 and the battery 3 will surely come into contact with each other.

Here, by placing a finger on the handle 7' and shifting the lid 7 backward, the engagement between the pawl 8 and the main body 1 is released. Further, at this time, the pin 9 has moved from the through-hole portion 11 to the upper part of the through-hole portion 12. By rotating the lid 7 by approximately 90 degrees using the handle 7', the lid 7 is opened as shown in FIG. 2, and the lower end 13 of the lid 7 comes into contact with the upper surface of the battery 3. moreover,
When the lid 7 is pushed downward along the through-hole portion 12 in the direction of the arrow (that is, toward the recess 5), the cathode side of the battery 3 enters the recess 5. At the same time, the anode side of the battery 3 is tilted upward so that the opening 6 protrudes, allowing the battery 3 to be taken out immediately.

[Effect of idea]

A recess is formed in the battery case, and the end of the battery located above the recess is pressed down by the lower end of the lid. Therefore, there is no need to use tape or the like as in the conventional case, and the battery can be quickly and easily removed by a series of operations such as opening the lid and then pressing down on the lid.

In the above embodiment, when opening the lid, the lid is moved backward to temporarily disengage the claw from the main body. However, other known configurations of engagement between the lid and the body are also possible. If the lid is not moved, the through hole does not need to have the shape of the example; for example, it is possible to use a gourd-shaped upper through hole and a lower through hole that communicate with each other, extending only in the direction of the recess. be. In this case, the pin rotates in the upper hole to open and close the lid, the pin elastically passes through the neck of the gourd-shaped hole, and the pin rotates in the lower hole to move the lid up and down. Moving.
